问题

最近准备使用Etcd开发一些分布式的应用，结果第一步就翻车了。
当信心满满的使用go mod开始go mod tidy时etcdv3有报错：

# github.com/coreos/etcd/clientv3/balancer/picker
undefined: balancer.PickOptions
undefined: balancer.PickOptions
# github.com/coreos/etcd/clientv3/balancer/resolver/endpoint
undefined: resolver.BuildOption
undefined: resolver.ResolveNowOption

解决办法

Etcd的代码和新版本的grpc(v1.27.0)冲突,再次施展替换大法，让项目使用老的grpc:

1

# 将 grpc 版本替换成 v1.26.0
go mod edit -require=google.golang.org/grpc@v1.26.0
# 获取 v1.26.0 版本的 grpc
go get -u -x google.golang.org/grpc@v1.26.0

通过以上的操作，即可解决以上问题。

建议

趁早换成 go.etcd.io/etcd/client/v3 吧!

Done.
